That is to be expected. LD_LIBRARY_PATH provides _run-time_ information for the system.

This is discussed in the 'R Extensions' manual. You could also look at what 'R CMD INSTALL --help' tells you, but this may be to terse. In a nutshell, you as the admin/user who place the GNU gsl in a 'unusual' location now have to tell R's gsl package where it can find them.
